BRICK PAVEMENT.

T 0 all whom it may concern:

the pavement at any one point even should the underlying foundation be uneven or otherwise faulty in construction.

For the purpose mentioned use is made of interlocked rows of bricks, the bricks in successive rows breaking joints, and each brick being provided at one side with a tongue and at the other side with a groove, the said tongue and groove extending from one end of the brick to the other end thereof, and the tongues of the bricks in one row of bricks fitting into the grooves of the adjacent joint-breaking bricks in the next row of bricks, so that each brick in each row is sustained.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a perspective view of the pavement; and Fig. 2 is an enlarged perspective view of one of the bricks.

The bricks A are laid in rows upon a suitable foundation B, from one curb C of the roadway to the other curb, and each brick is made of burnt clay, cement, artificial stone or other suitable material, and each brick is preferably about 3x6x9 inches. The bricks in succeeding rows break joints, as plainly indicated in Fig. 1, and the rows of bricks are interlocked one with the other, and for this purpose each brick A is provided at one side with a tongue D and at the other side with a groove E, the said tongue and groove extending from one end of the brick to the other end thereof.

tongue I) of a brick in one row of bricks fits into the groove of the adjacent joint-breaking bricks in the next row of bricks, and the tongue of each brick has its upper and lower faces parallel and beveled in a clownward and outward direction, and the top and bottom walls of each groove E are parallel and beveled upwardly and outwardly. Each groove E is of a depth approximately half the thickness of a brick, and the tongue I) is of a corresponding thickness, and by having the tongues and grooves D and E of the bricks beveled as described, the bricklayer is enabled'to slide the tongue D of a brick in adownward direction into the grooves E of adjacent joint-breaking bricks of a row of bricks already laid, as will be readily understood by reference to Fig. l.

By this downward movement of the brick to be laid, any tendency of dirt or sand to pass between the joints of adjacent rows of bricks is reduced to a minimum.

In practice, the bricks are laid in cement or other adhesive material, so that the bricks are securely fastened together on the cement setting and hardening, and by interlocking the rows of bricks as described, none of the bricks can settle or give way without breaking the whole structure, even should the foundation be uneven or otherwise faulty in construction.

By the arrangement described, the brick pavement can be readily laid on an ordinary road bed made of natural dirt. The pavelment is self-sustaining and by being laid in cement is waterproof, that is, water cannot penetrate to the underlying foundation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A pavement, comprising interlocked rows of bricks, the bricks in succeeding rows breaking joints and each brick being provided at one side with a tongue and at the other side with a gr0ove,the said tongue and groove extending from one end of the brick to the other end thereof and the tongue of a brick in one row of bricks fitting into grooves of the adjacent joint-breaking bricks in the next row of bricks, each groove being of a depth approximately half the thickness of a brick and each tongue being In testimony whereof I have signed my of a corresponding thickness, the tongue of name to this specification in the presence of each brick having its upper and lower faces two subscribing witnesses.

parallel and beveled downwardly and out- 7 CHARLES C. PETTIT. wardly, and the top and bottom walls of WVitnesses': the groove in each brick being parallel and G. L. Foo'r, beveled upwardly and outwardly. WV: I. HAHN.
